I narrowly missed becoming a member with my PowerGrips. At the end of a ride, I pulled into my garage and was moving very slowly to avoid hitting an object on the garage floor. I was about to lean left to dismount to the left when I lost my balance and my bike started tipping to the right. My right shoe was "clipped" in the PowerGrip and I wasn't able to extract it.

There is no doubt that I would have fallen onto the concrete floor. However I was close to the wall, threw out my arm, and caught myself about 1/3rd of the way down. As no part of my body, excepting for the bottom of my shoes, touched the floor, it was not a fall.
